I recently had a foundation repair crew lift a corner of my slab about 0.5". In the process, they somehow cracked my garabe slab (spiderweb cracks). They’re denying responsibility and their engineer said it was nothing to worry about. Is there anything I should do now? Otherwise, I plan to wait for Spring after seeing if winter affects it.
Do you have before/after photos to show they caused the cracks?
I’d get an independent assessment of the damage. It’s possible it’s just cosmetic like their engineer said.
If the damage is limited to a small area you could try to have that portion of the slab removed and repoured.
I have only after, because they assured me it wouldn’t happen. But they agree the cracks, which are all over, probably happened due to their work.
I would make sure to have that in writing.
